    摘要： The present invention relates to a nonwoven web comprising a plurality of loops. At least one of said loops having a loop circumference length to loop base length ratio that is greater than about 4:1. The loops may also have a base length less than 0.5 cm and a base length less than the maximum width of the loops. The present invention also relates to articles selected from the group consisting of disposable hygiene article and wipes comprising a nonwoven web wherein at least one region of the nonwoven web comprises loops in at least about 10% of the surface area of the nonwoven web. A method for producing a nonwoven web comprising a plurality of loops is also included. The method comprises the steps of providing a nonwoven web; providing means for moving fibers of the nonwoven web into the shape of a loop; and moving fibers of the nonwoven web into the shape of a loop.

    摘要： A fibrous product including a mixture of different shaped fibers is formed utilizing a spin pack assembly including a spinneret with at least two spinneret orifices having different cross-sections. In addition, the formation of the fibrous product is enhanced by controlling the pressure drop upstream from the spinneret orifices, which in turn facilitates effective control of fiber denier. A metering/distribution plate is preferably provided in the spin pack with channels having selected dimensions that control the pressure drop of molten polymer flowing through the spin pack. The metering/distribution plate can be retrofitted into existing systems and easily exchanged with other metering/distribution plates to enhance formation of the fibrous product with different fiber shapes.
